Patch Creator is a two part application to create and apply self-contained & (optionally) password & compressed patches for files already on the end-users machine. Only registered users can use the patches created using this program since the files on the machine are used to create the updated version. Updates to different versions of the same named files can be included in a single patch. Patches are based on actual file differences but you can include entire files. The Patch Applicator can also rename and delete specified files. 32 bit patches can write in-use files after reboot, write .reg entries, & use a .reg entry to locate The Target path for applying the patch. You can configure patches so that if one (or more) key files are not found the patch is Abandoned. The Patch Creator can save/retrieve setup data for easy replication of complex patch builds. There are no royalty fees.
